Mailbird’s pricing page buries its best deal. The lifetime license sits behind the subscription option, and if you don’t click through, you’ll miss the option that pays itself off in under three years. Since Mailbird launched its Mac app on the Apple App Store in September 2025 — expanding beyond Windows for the first time — the pricing question has gotten more relevant: one license now covers both platforms. Here’s exactly what each tier costs, what it locks, and which one you should buy.
Free Trial Limits
Mailbird’s free plan gives you one email account, Knowledge Base support only, and no time limit — but the single-account restriction defeats the product’s main value proposition, which is a unified inbox across multiple accounts.
Mailbird’s free tier is functional but constrained by design. Per the pricing page as of 2026-04-18:
- One email account only. If you have a personal Gmail and a work IMAP address, you can’t use both on the free tier. The multi-account unified inbox — which is the core reason most people download Mailbird — is locked behind paid.
- Knowledge Base support only. No live chat, no ticket support, no VIP queue.
- Core UI is accessible. You can verify that Mailbird’s interface, speed, and keyboard shortcuts work for you before paying anything.
Our take: the free tier is adequate for evaluation. Spend a week on one account to confirm the UI works for your workflow, then decide whether the paid tier is worth it. Staying on free long-term doesn’t make sense — the single-account limit defeats the product’s main value proposition.
One-Time License vs. Subscription
The one-time lifetime license at €73.80 pays itself off against the €27.60/year subscription in roughly 2.7 years. If you plan to use Mailbird for more than three years — realistic for a desktop email client — the lifetime license wins on cost.
This is the most important decision in the Mailbird pricing stack. Two paid options exist:
Premium — Yearly Subscription
- Listed at €2.30/user/month (billed annually, per the pricing page as of 2026-04-18)
- Marked as “50% off” from a regular monthly rate of €4.60/month
- Includes: unlimited accounts, VIP customer support, unlimited email tracking, email templates, custom apps, sender blocking, filters/rules
Premium — Pay Once (Lifetime License)
- Listed at €73.80 (one-time, per the pricing page as of 2026-04-18)
- Marked as “75% off” from a regular price of €295.20
- Includes everything in the yearly tier, plus an additional free Premium license
- Does not include lifetime updates by default — “Lifetime Updates” is a separate add-on at €65
Both tiers also offer optional add-ons:
- Leave Me Alone integration: €55 (bundles Leave Me Alone’s inbox cleanup into the Mailbird purchase flow)
- Lifetime Updates: €65 (guarantees all future major versions at no extra charge)
The breakeven math: at €2.30/month on the yearly plan, you pay €27.60/year. The lifetime license at €73.80 pays itself off in roughly 2.7 years. If you plan to use Mailbird for more than three years — which is plausible given it’s a desktop client, not a web service that disappears — the lifetime license wins on cost.
One caveat: “lifetime” means the current version plus any minor updates included in that release cycle. If Mailbird releases a major new version in year three, you may need to pay again unless you also purchased Lifetime Updates. We can’t verify how Mailbird has historically handled major version upgrades because their public changelog doesn’t clearly document this policy. If long-term cost certainty matters to you, add the €65 Lifetime Updates at purchase.
Current Tier Comparison
Three tiers exist: Free (one account), Premium Yearly (~€27.60/year), and Premium One-Time (€73.80 lifetime). All paid plans include a 14-day money-back guarantee and cover both Windows and Mac.

Where To Find a Discount
Mailbird runs promotional pricing periods where the lifetime license is discounted 75% and the yearly plan 50%. These aren’t permanent baseline prices, but they appear frequently enough that waiting for a “better deal” rarely pays off.
Seasonal promotions. Mailbird runs discounts periodically — the current “75% off one-time” and “50% off yearly” banners on the pricing page suggest a promotional period is active as of this writing. Whether those higher “regular” rates are genuinely the baseline or are notional reference prices to make the discount look larger, we can’t say with certainty. The practical takeaway: if the price you see is acceptable, buy now rather than waiting.
Affiliate codes and coupon sites. Most “Mailbird coupon” results in search are affiliate pages recycling the same vendor-provided codes. You’re not getting a special rate beyond what’s already on the homepage.
Volume licensing. If you’re purchasing 2+ seats (a team or a household), contact Mailbird directly or check the volume discount page. 5–25% off is available on multi-seat purchases per the pricing page.
Referral. Mailbird has historically offered referral credits. Check your account dashboard if you’re already a user — the mechanism has appeared and disappeared across versions.
What we don’t recommend: buying through grey-market key resellers. Mailbird is not a retail-boxed product; keys from unofficial sources are either leaked, revoked, or volume keys that violate the EULA.
Is It Worth the Price?
At €73.80 for a lifetime license, Mailbird is competitively priced for a Windows desktop email client. If you’re already in the Microsoft 365 ecosystem, Outlook’s marginal cost is $0 and Mailbird needs to be a meaningfully better experience to justify the spend.
The nearest comparison points:
- Outlook is included with Microsoft 365 at ~€7/month (personal) or ~€9/month (family), which covers Word, Excel, and 1 TB OneDrive. If you already pay for Microsoft 365, Outlook costs you zero additional dollars.
- Thunderbird is free, open source, and in active development. The 2023 Supernova redesign significantly improved the UI — it’s no longer the dusty backup option.
- eM Client has a free tier (2 accounts) and a one-time paid option in a similar price range.
Mailbird’s value case is not price — it’s the integrations panel and UI polish. If you manage two or more email accounts and want Google Calendar, Slack, Todoist, and WhatsApp accessible in the same window without alt-tabbing, Mailbird is genuinely useful. We use it as a primary client on Windows and the unified inbox is the feature we miss most on other machines.
Where it doesn’t win on value:
- If you’re already in the Microsoft 365 ecosystem, Outlook’s Exchange and Teams integration is hard to beat.
- If cost is the primary driver, Thunderbird is free and substantially better than it was three years ago (see our Mailbird vs Thunderbird comparison).
- If you’re primarily on Mac or Linux, Mailbird isn’t the right tool — the Mac version has historically trailed Windows, and there’s no Linux build at all.
For a Windows-native user who manages multiple email accounts and values a fast, clean interface: yes, €73.80 is worth it. For everyone else: consider the alternatives first.
When This Doesn’t Apply
Mailbird’s pricing is only relevant if you’re on Windows or Mac. Linux users have no Mailbird option. Microsoft 365 subscribers who are deep in the Exchange ecosystem will find Outlook’s zero marginal cost hard to beat.
There are situations where evaluating Mailbird’s pricing isn’t the right exercise:
Linux users. Mailbird has no Linux build. Full stop — the pricing question doesn’t apply.
Microsoft 365 subscribers who live in Exchange. If your organization runs Teams and SharePoint on M365, Outlook is the connective tissue and nothing else replicates that depth. The marginal cost of Outlook for an existing M365 subscriber is $0. Paying €73.80 for a different client is only worth it if Mailbird’s unified inbox and app panel are dramatically better for your workflow.
Users who want open-source verification. Mailbird is proprietary software. If you need to audit what data the application sends, you can’t — the source code isn’t available. Thunderbird or Betterbird are the right answers for that threat model.
One-account users. If you have a single email account and no immediate plans to add more, the free tier is sufficient for evaluation. The paid tier’s value is almost entirely in the multi-account unified inbox.

LinkedInFrequently asked questions
Does Mailbird have a free plan? — one account, no time limit
Yes — one email account, Knowledge Base support only, unlimited time. It’s enough to evaluate the UI, but the single-account limit makes it impractical as a primary client for most people.
Is the Mailbird one-time license really lifetime? — major version caveat
It covers the current major version and included minor updates. Future major versions may require an additional purchase unless you add “Lifetime Updates” (€65) at checkout. We recommend adding it if you want long-term cost certainty.
Does Mailbird work on Mac? — yes, since September 2025
Yes — Mailbird launched on the Apple App Store in September 2025. The cross-platform license covers both Windows and Mac. Historically the Mac version has lagged Windows in features; check the current changelog before buying specifically for Mac use.
Can I get a refund if I don’t like it? — 14-day guarantee
Yes — 14-day money-back guarantee on paid plans, per the pricing page. We haven’t personally tested the refund process.
Are there student or nonprofit discounts? — not listed publicly
Not listed on the public pricing page as of 2026-04-18. Contact their support directly to ask — it’s worth trying before buying at full price.
What’s included in the “additional free license” on the one-time plan? — extra seat
The Premium One-Time plan includes one additional free Premium license — effectively a second seat at no extra cost. Useful for a partner, family member, or a second machine.
